Fix it permanentlywith Weatherford casing repair and isolation.
Cased-hole, mature-field challenges
Our services are designed to remediate your cased-hole issues, whatever the application.
• Corroded or eroded casing• Water shutoff• Zonal isolation• Perforation isolation• Split or parted casing• Worn casing• Collar leaks• Buckled or deformed casing• Thief-zone elimination• Lateral and sidetrack isolation• Well deepening• Refracturing
Why Weatherford?
Industry-leading technologyWe have a full suite of technologies that reliably, quickly, and safely restore your wellbore integrity, minimize your lifting costs, and maximize your reservoir output.
Efficient, full-service capabilities By providing you with a single source, Weatherford increases efficiency. You’ll get one company that can design and coordinate your entire remediation operation. For optimal results, we collaborate with you to develop a plan, select the best technology for the job, and coordinate installation at the job site.
Reduced operating costs Through our solid-expandable technology, we can help you make long-term casing repairs that are more cost efficient than short-term, squeeze-cementing jobs. Weatherford’s MetalSkin® cased-hole liner system or HOMCO® internal casing patch provides a permanent fix that lowers cumulative well operating costs.
Solid results from around the worldUSA (North Dakota)Casing Repair and Isolation Services Fix Leaky 150-ft SectionWeatherford provided the single-source solution—including fishing, wireline, and tubular running services. Our MetalSkin® liner repaired a 150-ft (46-m) casing section, bringing the well to full quality and health, safety, and environmental (HSE) integrity standards in less than 2 weeks.
ColombiaMetalSkin Liner Seals Off Water-Producing Zone in Less Than 24 Hours Weatherford services maximized production and reduced downtime significantly with the MetalSkin liner, which was installed faster than a scab liner.
CongoWeatherford Services Eliminate Produced Water from Corroded Interval in Shallow, Offshore WellWeatherford fishing and rental, wireline, and tubular running services, and our H2S-resistant MetalSkin liner system covered a corroded interval and brought the well to full HSE integrity with no drillout needed. Designed around platform limitations, a specialized jack system eliminated the workover-rig requirement during liner installation.
EuropeMetalSkin Liner Restores Production in Offshore Well with Severely Corroded Liner Weatherford ran and expanded a 2,967-ft (904-m), 7 5/8-in. × 9 5/8-in. MetalSkin liner. The liner system reduced operating expenses by 50 percent and rig time by 28 days, compared to a slot-recovery alternative. The flexible system enabled the client to run additional liner after discovering casing leaks deeper in the well.
IraqMetalSkin Liners, CLEARMAX™ Cleaning Services Remediate Casing, Maintain Maximum ID in 29 HoursWeatherford ran our MAX-Blade™ casing scraper and MAX-Brush™ assembly to 3,494 ft (1,065 m), preparing the casing interior for two 7 5/8- × 9 5/8-in. MetalSkin liners. The liners provided one-trip installation with no additional drillout, hydraulically isolated the perforated intervals, and maximized the pass-through diameter.
MalaysiaMetalSkin Liner Restores Casing Integrity, Saves Offshore Well from AbandonmentAfter unsuccessful cement squeeze attempts, Weatherford installed a 7 5/8-in. × 9 5/8-in. MetalSkin liner and then ran an IPP® inflatable production packer below it. The liner re-established the integrity of the 9 5/8-in. parent casing, enabling the operator to recomplete the well as a water-alternating-gas injector.

Take advantage of advanced technologies that help pinpoint casing problems, water-
production sources, wellbore obstructions, and bypassed production opportunities.
The UltraView™ tool simultaneously delivers 360° ultrasonic cement and casing
inspections in real time. The CalView™ multi-sensor caliper captures high-resolution
samples at 10 times the industry standard, and the FluxView™ tool reveals internal
and external casing damage using 360° magnetic-flux, sensor-array technology.
These three tools are part of our SecureViewSM suite of casing evaluation tools.

integrity. In addition, this technology saves
you money in the long run, while giving you an
extra margin of safety and security.
Our MetalSkin® cased-hole liners isolate
damaged casing and seal off unwanted
perforations and formation fluids. With
single-trip installation and no drillout
required, both rig and nonproductive time
are significantly reduced. In many cases,
liners can be installed in one day, enabling
you to test immediately and get the well
back on production.
